DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1A is a schematic diagram of a water supply in accordance with oneembodiment of the instant disclosure. Referring to FIG. 1A, the watersupply 100 can output a flow F1, and can be the water tap, the toilet,or the shower nozzle. The water supply 100 includes a body 110, agesture sensor 120, and a control valve 130. The control valve 130 isconfigured on the body 110 to control the flow F1. The control valve 130can be the solenoid valve. The gesture sensor 120 can sense variousgestures performed by the hand H1 of the user and send the correspondingcontrol commands to the control valve 130 according to the gestures.Thus, the control valve 130 can be controlled to release or stop theflow F1, or to change the discharge or output amount of the flow F1.

It worth noting that, the above mentioned output amount is the volumeoutputting from the water supply 100. The calculating unit of the outputamount can be the volume unit, such as liter, milliliter, or gallon, orweight unit, such as kilogram, gram, or pound. In addition, the amountof the output amount is determined by the period of the control valve130 turned on to supply the flow F1. The longer the control valve 130 isturned on to supply the flow F1, the larger amount of the output amountis. On the contrary, the shorter the control valve 130 is turned on tosupply the flow F1, the smaller amount of the output amount is.

The body 110 can store water and include a water outlet 112 and a space114 to retain water. The water inside the space 114 can flow out fromthe water outlet 112, so as to supply the flow F1. In addition, the body110 shown in FIG. 1A includes a tank 118, an output tube 116 a, and aninput tube 116 b. The output tube 116 a and the input tube 116 b areconfigured on the tank 118. The output tube 116 a includes the wateroutlet 112. The input tube 116 b can guide the water into the space 114.

The body 110 shown in FIG. 1A includes the tank 118, the output tube 116a and the input tube 116 b. However, the body 110 can be just a tubewithout the tank 118 in other embodiment. The body 110 can have varioustypes in different embodiments. FIG. 1A shows only one type of body 110as example to illustrate.

FIG. 1B is a circuit block diagram of the water supply shown in FIG. 1A.Referring to FIGS. 1A and 1B, the gesture sensor 120 includes a lightsource 121, an image sensing unit 122, and a processing unit 123. Theprocessing unit 123 is electrically connected to the light source 121and the image sensing unit 122. The light source 121 can emit the lightE1 to the hand H1 of user. The light E1 can be the visible light or theinvisible light. The visible light can be the infrared ray. Moreover,the light source 121 can be the infrared light-emitting diode (InfraredLED).

The image sensing unit 122 is adjacent to the light source 121 and cancapture the image, especially the dynamic image. The above mentiondynamic image is formed by the reflection of the light E1. Thus, theimage sensing unit 122 can capture the image formed by the invisiblelight, such as the image formed by the infrared ray. In addition, theimage sensing unit 122 can be the complementarymetal-oxide-semiconductor sensor (CMOS Sensor) or the charge-coupleddevice (CCD).

While the hand H1 of the user perform several control gestures, such asmaking a fist, opening a palm, wave a hand, or turn the palm in thecounterclockwise direction C1 or the clockwise direction C2 (as shown inFIG. 1A), the hand H1 can reflect the light E1 to be the light R1. Theimage sensing unit 122 can receive the light R1, and capture the imagefrom the light R1. Thus, the image sensing unit 122 can capture variousgesture images from the various control gestures performed by the handH1. The gesture images are formed by reflecting the light E1 (which isthe light R1).

It's worth noting that, in the present embodiment, the gesture sensor120 includes the light source 121 to emit the light E1. However, inother embodiment, the gesture sensor 120 can be without the light source121 and the image of the hand H1 can be captured by the image sensingunit 122 directly. Specifically, the hand H1 can reflect the externallight, such as the light source from indoor or the sunlight fromoutdoor. The image sensing unit 122 can capture the image from theexternal light reflected by the hand H1. Similarly, the image sensingunit 122 can also capture various gesture images from the controlgesture performed by the hand H1. Therefore, the above mentioned gestureimage is not limited to be formed by the reflection of the light E1(which is light R1). The above mentioned gesture image can also beformed by the external light source.

The processing unit 123 is electrically connected to the control valve130 by the wire, or built up a signal link with the control valve 130 bythe wireless technique, such as Bluetooth. The processing unit 123sending several control command to the control valve 130 to command thecontrol valve 130 release or stop the flow F1 or change the discharge orthe output amount of the flow F1. The processing unit 123, such as thedigital signal processor (DSP), can be able to judge whether there isthe gesture image among various images captured by the image sensingunit 122 corresponding to the control command according to thealgorithm, so as to recognize to these control gestures.

The processing unit 123 saves the recognition data. The algorithmutilized by the processing unit 123 to recognize the gestures can be theobject recognition algorithm or the object tracking algorithm. While theprocessing unit 123 utilizes the object recognition algorithm, theprocessing unit 123 can judge whether there is the object among theimages captured by the image sensing unit 122 shaped like the hand. Theprocessing unit 123 can further judge whether the gesture of the objectis one of the gesture image. While the processing unit 123 conforms thatthe gesture of the object is the same as one of the gesture images, theprocessing unit 123 can send the control command correspond to thegesture image to the control valve 130, so as to control the controlvalve 130.

While the processing unit 123 utilizes the object tracking algorithm,the processing unit 123 can judge whether the motion trace of the objectamong the successive images captured by the image sensing unit 122 isconform to one of the gesture images. The above-mentioned object canhave a specific shape, such as the shape of the hand or the shape of theelectronic device like mobile phone or the game console. While theprocessing unit 123 conform that the motion trace of the object is thesame as one of the motion of the gesture images, the processing unit 123can send a control command correspond to the gesture image to controlthe control valve 130.

The control command sent by the processing unit 123 includes thefirst-discharge command or the second-discharge command. The controlvalve 130 changes the discharge of the flow F1 as the first dischargeaccording to the first-discharge command, and change the discharge ofthe flow F1 as the second discharge according to the second-dischargecommand. The first discharge is larger than the second discharge. Theprocessing unit 123 can command the control valve 130 to change thedischarge of the flow F1 according to the first-discharge command or thesecond-discharge command.

In the embodiment shown in FIG. 1A, the gesture image correspond to thefirst-discharge command is the palm counterclockwise rotation (turn thehand H1 in the counterclockwise direction C1), and the gesture imagecorrespond to the second-discharge command is the palm clockwiserotation (turn the hand H1 in the clockwise direction C2). Thus, whilethe user open the hand H1 and perform the palm in the counterclockwisedirection C1, the control valve 130 can adjust the discharge of the flowF1 as the high discharge (first discharge). In contrast, while the useropens the hand H1 and turns the palm in the clockwise direction C2, thecontrol valve 130 can adjust the discharge of the flow F1 as the lowdischarge (second discharge). Accordingly, the user can gain differentdischarge of the flow F1 by turning the palm in the counterclockwisedirection or clockwise direction.

In addition, in other embodiment, the control commands can includes thedecrement command or the increment command. For instance, while the handH1 performs the gesture of the palm counterclockwise rotation, theprocessing unit 123 sends the increment command to command the controlvalve 130 to increase the discharge of the flow F1. In contrast, whilethe hand H1 performs the gesture of the palm clockwise rotation, theprocessing unit 123 sends the decrement command to command the controlvalve 130 to decrease the discharge of the flow F1. Therefore, while theuser want the large discharge of the flow F1, the hand H1 of the usercan perform one or successive gestures of the palm counterclockwiserotation. While the user want the small discharge of the flow F1, thehand H1 of the user can perform one or successive gestures of the palmclockwise rotation.

The control commands can includes water supply command and the wateroutage command. The water supply command and the water outage commandare corresponding to different kinds of gesture images. The water supplycommand is command the control valve 130 to supply the flow F1. Thewater outage command is command the control valve 130 to stop supply theflow F1. Specifically, while the control valve 130 starts up and theflow F1 is not supplied, the hand H1 can perform the control gesturecorresponding to the water supply command in front of the gesture sensor120, so that the image sensing unit 122 can capture the gesture image.The processing unit 123 sends the water supply command to the controlvalve 130 according to the gesture image. At this moment, the controlvalve 130 open the water outlet 112 according to the water supplycommand to supply the flow F1.

While the flow F1 is supplied and the user wants to stop the flow F1,the control gesture corresponding to the water outage command can beperformed in front of the gesture sensor 120, so that the image sensingunit 122 can capture the gesture image. The processing unit 123 can senda water outage command to the control valve 130 according to the gestureimage. Meanwhile, the control valve 130 can shut off the water outlet112 to stop supply the flow F1 according to the water outage command.

The control commands can further includes a first water-output commandor a second water-output command. The control valve 130 can change theoutput amount of the flow F1 as the first output amount according to thefirst water-output command and as the second output amount according tothe second water-output command. The first output amount is larger thanthe second output amount. Therefore, the processing unit 123 can commandthe control valve 130 to change the output amount of the flow accordingto the first water-output command or the second water-output command.Moreover, the processing unit 123 can setup the sustained time which thecontrol valve supply the flow F1 according to the first water-outputcommand and the second water-output command, so as to change the outputamount of the flow F1.

For instance, according to the first water-output command, theprocessing unit 123 can setup the control valve 130 to continuouslysupply the flow F1 for 10 second. In addition, according to the secondwater-output command, the processing unit 123 can setup the controlvalve 130 to continuously supply the flow F1 for 5 second. Thus, on thepremise that the discharge of the flow F1 doesn't change, the firstoutput amount is larger than the second output amount, and the controlvalve 130 can supply different output amounts.

The water supply 100 further includes the display device 140. Thedisplay device 140 is electrically connected to the processing unit 123,or built up a signal link with the processing unit 123 by the wirelesstechnique, such as Bluetooth. The display device 140 can display thecondition of the water supply 100, such as the open up condition or theshutdown condition of the water supply 100. The open up condition meansthat the control valve 130 is switch on and be able to receive thecommand from the processing unit 123 to release or stop the flow F1 orchange the discharge or the output amount of the flow F1. Therefore,while the water supply 100 is in the open up condition, the controlvalve 130 can control the flow F1 according to the control gestureperformed by the user.

On the other hand, the shutdown condition means that the control valve130 is switch off. While the water supply 100 is in the shutdowncondition, the control valve 130 shut off the water outlet 112 and stopsupplying the water until the control valve 130 receive the open upcommand from the processing unit 123. The open up command corresponds tothe gesture performed by the user. The image sensing unit 122 cancapture the open up gesture image formed by the light R1 or the externallight among the open up gesture. The processing unit 123 can command thedisplay device 140 to display the open up condition according to theopen up gesture image and open up the control valve 130.

While the water supply 100 is in the shutdown condition, the controlvalve 130 would not start up by the gesture of the user, unless the handH1 performs the open up gesture. Moreover, it's worth noting that, theopen up command is different from the above-mentioned water supplycommand. The open up command is utilized to open up the control valve130, so that the control valve 130 can receive the command of theprocessing unit 123. The water supply command is only utilized tocommand the control valve 130 to release the flow F1. Therefore, theopen up command to start up the control valve 130 is different from thewater supply command to release the flow F1.

In the embodiment shown in FIG. 1A, the display device 140 can includethe light-emitting components 142 and the indicator translucent panel144. The light-emitting components 142 can be such as the light-emittingdiode (LED) or the cold cathode fluorescent lamp (CCFL). The indicatortranslucent panel 144 can be the light transmissivepolymethylmethacrylate substrate (PMMA substrate) or the glasssubstrate. The indicator translucent panel 144 can display thecorresponding gestures and the functions according to the variouscommands (such as the open up command, the first-discharge command, thesecond-discharge command, the water supply command, and the water outagecommand).

For instance, the surface of the indicator translucent panel 144 canshow the letters or the patterns to represent the gesture of thecounterclockwise rotation corresponding to the high discharge (firstdischarge) of the flow F1, and gesture of the clockwise rotationcorresponding to the lower discharge (second discharge) of the flow F1.Therefore, the user can manipulate the water supply 100 according to thecontent shown in the display device 140. Besides, in other embodiment,the display device 140 can be the liquid crystal display or the organiclight-emitting diode display. Thus, the indicator translucent panel 144can be omitted in the display device 140.

FIG. 1C is a schematic diagram of the water supply shown in FIG. 1A in ashutoff condition. Referring to FIGS. 1A and 1C, in the presentembodiment, while the water supply 100 is in the open up condition, theprocessing unit 123 can command the display device 140 to display theopen up condition according to the open up gesture image. Meanwhile, thelight-emitting components 142 emits light toward the indicatortranslucent panel 144, so as to light up the indicator translucent panel144, as shown in FIG. 1A.

In contrast, while the water supply 100 is in a shutdown condition, theprocessing unit 123 can command the display device 140 to display theshutdown condition according to the shutdown gesture image. The shutdowncondition corresponds to the shutdown gesture image performed by thehand H1. The image sensing unit 122 can capture the shutdown gestureimage formed by the light R1 or external light from the shutdowngesture. The processing unit 123 can shut down the display device 140according to the shutdown gesture image and send the shut down commandto the control valve 130. Thus, the display device 140 display theshutdown condition, and the light-emitting components 142 stop emittinglight, as shown in FIG. 1C. Then, the control valve 130 is in theshutdown condition.

In addition, in the present embodiment, the open up gesture imagecorresponding to the open up command can be opening the palm (as shownin FIG. 1A). The shutdown gesture image according to the shutdowncommand can be making a first (as shown in FIG. 1C). Thus, the surfaceof the indicator translucent panel 144 can show the letters or thepatterns to represent the gesture of opening the palm corresponding tothe start up of the water supply 100 or the gesture of making a firstcorresponding to the shutdown of the water supply 100.

It's worth noting that, in the present embodiment, the control gestureof the first-discharge command and the second-discharge command are thepalm counterclockwise rotation and the palm clockwise rotationrespectively. The open up gesture corresponding to the open up commandis opening the palm. The shutdown gesture corresponding to the shutdowncommand is making a fist. Nevertheless, in other embodiment, thefirst-discharge command and the second-discharge command can becorresponding to be other kinds of gesture rather than turning the palmin the counterclockwise direction and clockwise direction, such as wavethe hand. In addition, the open up gesture and the shutdown gesture canbe other gesture rather than opening the palm and making the fist.Therefore, the open up gesture, the shutdown gesture, and the controlgestures mentioned above can be making the fist, opening the palm,waving the hand, turning the palm in the clockwise direction, turningthe palm in the counterclockwise direction or the combination of othergestures at random. The present invention does not limit to the actionof the open up gesture, the shutdown gesture, and the control gestures.

It's worth noting that, the water supply 100 can be the water tap or thetoilet, and the gesture sensor 120 can apply on the water tap.Therefore, the following paragraph takes the FIGS. 2A, 2B, and 3 as anillustration to detail description the embodiment which takes the watersupply 100 as the water tap. In addition, the water tap in FIGS. 2A, 2B,and 3 has the similar technique features as the water supply 100. Thesame technique features of the water tap and the water supply 100 suchas the method of gesture sensor recognizing the gesture is omittedthereof.

FIG. 2A is a cross-section view of a water tap in accordance with oneembodiment of the instant disclosure. Referring to FIG. 2A, the watertap 200 includes the tap body 210, the gesture sensor 120, and thecontrol valve 230. The control valve 230 is configured on the tap body210 to control the flow F2 outputting from the tap body 210. The gesturesensor 120 can control the control valve 230 according to the gestureperformed by the hand H1 of the user, so as to operate the water tap 200according to the gesture performed by the hand H1.

The tap body 210 includes a water outlet 212 to provide the flow F2. Thecontrol valve 230 is configured on the tap body 210 to control the flowF2. The control valve 230 can be the solenoid valve. The gesture sensor120 is atop of the water outlet 212. The gesture sensor 120 includes thelight source 121, the image sensing unit 122, and the processing unit123. In the present embodiment, the processing unit 123 can electricallyconnect to the control valve 230 by the wires W1. However, in otherembodiment, the processing unit 123 can built up a signal link with thecontrol valve 130 by the wireless technique, such as Bluetooth. Thegesture sensor 120 can send the control command to control the controlvalve 230 by the wires W1 or the wireless technique.

The light source 121 can send out the light E1 to the hand H1 of theuser. After reflecting by the hand H1, the light E1 can be the light R1.By utilizing the light E1, the image sensing unit 122 can capturevarious gesture images from the various control gestures performed bythe hand H1. The control gestures includes making a fist, opening thepalm, waving the hand, turning the palm in clockwise direction, turningthe palm in the counterclockwise direction, or other kinds of gestures.The gesture image is formed by the reflection of the light E1(which isthe light R1). The processing unit 123 can send several control commandto the control valve 230 according to the gesture images. Thus, thegesture sensor 120 can control the control valve 230 according to thegesture performed by the hand H1. Besides, the above-mentioned gestureimages can also be formed by the external light reflected by the handH1.

The control command can include the decrement command or the incrementcommand. Specifically, the control valve 230 can decrease the dischargeof the flow F2 progressively according to the decrement command, andincrease the discharge of the flow F2 progressively according to theincrement command. The decrement command and the increment commandcorrespond to different control gestures respectively. For instance, inthe embodiment shown in FIG. 2A, the control gesture corresponding tothe increment command can be turning the palm in the counterclockwisedirection C1. The control gesture corresponding to the decrement commandcan be turning the palm in the clockwise direction C2.

As above mentioned, while the gesture sensor 120 senses the gesture ofturning the palm in counterclockwise direction C1 performed by the handH1, the image sensing unit 122 can capture the gesture image (the palmcounterclockwise rotation) by reflecting the light E1 or the externallight. The processing unit 123 can send the increment command to thecontrol valve 230 according to the gesture image. After that, thecontrol valve 230 can increase the discharge of the flow F2 according tothe increment command.

While the gesture sensor 120 sense the gesture of turning the palm inthe clockwise direction C2 performed by the hand H1, the image sensingunit 122 can capture gesture image (the palm clockwise rotation) byreflecting the light E1 or the external light. The processing unit 123can send the decrement command to the control valve 230 according to thegesture image. After that, the control valve 230 can decrease thedischarge of the flow F2 according to the decrement command. Thus it canbe seen that the gesture sensor 120 can control the control valve 230according to the palm counterclockwise rotation and the palm clockwiserotation, and further control the increasing or the decreasing dischargeof the flow F2.

Moreover, similar to the above-mentioned water supply 100, the controlcommand can include the first-discharge command, the second-dischargecommand, the first water-output command, and the second water-outputcommand. The first-discharge command, the second-discharge command, thefirst water-output command, and the second water-output commandcorrespond to different control gestures respectively. The controlgestures can be making the fist, opening the palm, waving the hand, andthe combination of other gestures at random. The image sensing unit 122can capture the gesture image from the gestures. The processing unit 123can send the first-discharge command, the second-discharge command, thefirst water-output command and the second water-output command to thecontrol valve 230 according to the gesture images.

The first-discharge command and the second-discharge command areutilized to change the discharge of the flow F2 respectively. The firstwater-output command and the second water-output command are utilized tochange the output amount of the flow F2 respectively. Specifically, thecontrol valve 230 can change the discharge of the flow F1 as the firstdischarge according to the first-discharge command, and change thedischarge of the flow F1 as the second discharge according to thesecond-discharge command. The first discharge is larger than the seconddischarge. The control valve 230 can change the output amount of theflow F1 as the first output according to the first water-output command,and change the output amount of the flow F1 as the second outputaccording to the second water-output command. The first output amount islarger than the second output amount. In addition, the control valve 230can determined the first output amount and the second output amount bychanging the duration of opening the flow F2.

In addition, similar to the above mentioned water supply 100, thecontrol command includes the water supply command or water outagecommand. The water supply command and the water outage commandcorrespond to two of the gesture images respectively. The water supplycommand is utilized to command the control valve 230 to release the flowF2, and the water outage command is utilized to command the controlvalve 230 to stop the flow F2. The processing unit 123 can send thewater supply command or the water outage command to the control valve230 according to different gesture images. The control valve 230 canstart up the water outlet 212 to release the flow F2 according to thewater supply command. In contrast, the control valve 230 can shut offthe outlet 212 to stop releasing the flow F2 according to the wateroutage command.

While the user wants the water tap 200 supplying the water to generatethe flow F2, the user can perform the control gesture corresponding tothe water supply command in front of the gesture sensor 120. Then, thegesture sensor 120 can control the control valve 230 to release the flowF2. While the user wants to shut off the water tap 200 to stop the flowF2, the user can perform the control gesture corresponding to the wateroutage command in front of the gesture sensor 120. Then, the gesturesensor 120 can control the control valve 230 to stop the flow F2.Therefore, the hand H1 of the user can start up or shut off the watertap 200 by the gesture without touching the water tap 200, so as toreduce the contact chance between the hand H1 and the bacteria.Moreover, control gestures corresponding to the water supply command andthe increment command can be the same, and the control gesturescorresponding to the water outage command and the decrement command canbe the same.

In the present embodiment, the gesture sensor 120 is configured on thetap body 210, and atop of the water outlet 212, as shown in FIG. 2A.Referring to FIG. 2A, the gesture sensor 120 on the top of the wateroutlet 212 is configured on the upper portion of the tap body 210 anduncovered by the tap body 210. Thus, the user can find out the positionof the gesture sensor 120 easily. In addition, the hand H1 can performseveral gestures in front of the tap body 210, so as to operate thewater tap 200 conveniently.

The water tap 200 can further include the display device 240. Thedisplay device 240 can electrically connected to the processing unit123. In addition, the display device 240 can built up a signal link withthe processing unit 123 by the wireless technique, such as Bluetooth. Inthe present embodiment, the structure of the display device 240 issimilar to the structure of the above mentioned display device 140essentially. That is to say, the display device 240 includes thelight-emitting component (not shown in FIG. 2A) and the indicatortranslucent panel (not shown in FIG. 2A). Thus, the description aboutthe structure of the display device 240 is omitted thereto. In addition,in other embodiment, the display device 240 can be the liquid crystaldisplay or the organic light-emitting diode display, thus the displaydevice 240 shown in FIG. 2A can be without the indicator translucentpanel.

The display device 240 includes the display panel 242. The display panel242 can represent gestures and functions corresponding to variouscommands (such as the first-discharge command, the second-dischargecommand, the water supply command, and the water outage command) byshowing the letters or the patterns. While the display device 240includes the indicator translucent panel, and the indicator translucentpanel includes the display panel 242, the letters or the patterns can beshown on the display panel 242. While the display device 240 is theliquid crystal display or the organic light-emitting diode display, thedisplay panel 242 can show the scene containing the above mentionedletters or the patterns.

FIG. 2B is a schematic diagram of a display device in the view from thedisplay panel shown in FIG. 2A. Referring to FIGS. 2A and 2B, in thepresent embodiment, the display panel 242 can display the letters suchas “waving the hand”, “making the fist”, “turning the palm in theclockwise direction”, and “turning the palm in the counterclockwisedirection” to represent the gesture. In addition, the display panel 242can also display the letter such as “start up”, “shut off”, “opening thewater tap, increasing the discharge”, and “shutting off the water tap,decreasing the discharge” corresponding to the function of the gestures.

Thus, the user can figure out from the display panel 242 that the handH1 has to perform the gesture of waving hand when start up the water tap200. On the other hand, the hand H1 has to perform the gesture of makinga first when shut off the water tap 200. When open the water tap orincrease the discharge of the flow F2, the hand H1 has to perform thegesture of the counterclockwise rotation. When close the water tap ordecrease the discharge of the flow F2, the hand H1 has to perform thegesture of the palm clockwise rotation.

Moreover, the display device 240 can display the condition of the watertap 200, such as displaying the water tap 200 is in the open upcondition or in the shutdown condition. Similar to the above mentionwater supply 100, the open up condition means that the control valve 230is opening up, and is able to accept the control command (such as thefirst-discharge command, the first water-output command, and the watersupply command) sent by the processing unit 123 to release or stop theflow F2, or to change the discharge or the output amount of the flow F2.

The shutdown condition means that the control valve 230 is shuttingdown. While the water tap 200 is in the shutdown condition, the controlvalve 230 can shut down the water outlet 212 and maintain the shuttingdown condition until the control valve 230 receive the open up commandsent by the processing unit 123 to start up. The open up commandcorresponding to the open up gesture performed by the user, the imagesensing unit 122 can capture the open up gesture image formed by thelight R1 or external light from the open up gesture. The processing unit123 sends the open up command according to the open up gesture image tomake the display device 140 to display the open up condition and startup the control valve 130.

While the water tap 200 in the shutdown condition, the control valve 230would not start up by gesture of the user, unless the hand H1 performsthe open up gesture. Moreover, the open up command is utilized to startup the control valve 230, so that the control valve 230 can becontrolled by the processing unit 123. However, the water supply commandis utilized to command the control valve 230 to release the flow F2.Thus, the above mentioned open up command is different from the watersupply command.

Concerning about above mention shutdown condition, the image sensingunit 122 can capture the shutdown gesture image formed by reflecting thelight E1 or external light from the shutdown gesture performed by thehand H1. The processing unit 123 can shut off the display device 240,such as making the light-emitting component of the display device 240 tostop emitting according to the shutdown gesture image. In addition, theprocessing unit 123 can send the shutdown command to the control valve230 according to the shutdown gesture image, so as to make the controlvalve 230 in the shutdown condition. Moreover, the above mentioned openup gesture and the shutdown gesture can be making the fist, opening thepalm, waving the hand, turning the palm in the clockwise direction,turning the palm in the counterclockwise direction, or the combinationof other gestures at random.

FIG. 3 is a cross-section view of a water tap in accordance with theother embodiment of the instant disclosure. Referring to FIG. 3, thewater tap 300 in the present embodiment is similar to the water tap 200mentioned above. The description of the similar technique features ofboth the water tap 200 and 300 is omitted therefore. The differencebetween the water tap 200 and 300 is that the gesture sensor 120 of thewater tap 300 is configured beneath the water outlet 212 and out of theflowing path of the flow F2, On the other hand, the tap body 210 coversthe gesture sensor 120 as shown in FIG. 3.

Since the tap body 210 covers the gesture sensor 120, the tap body 210can shield off partial external light emit into the image sensing unit122 of the gesture sensor 120. The tap body 210 can decrease some of thebackground-light noise emitting into the image sensing unit 122, so asto increase the sensing accuracy of the gesture sensor 120. Therefore,the chance that the water tap 300 made the error owning to the influenceof noise can be decreased.

In addition, in the present embodiment, the gesture sensor 120 canelectrically connect to the control valve 230 and the display device 240by wires W2, so that the processing unit 123 can send the command to thecontrol valve 230 and the display device 240. Nevertheless, in otherembodiment, the processing unit 123 can built up a signal link with thecontrol valve 230 and the display device 240 by the wireless technique,such as Bluetooth. Hence, the gesture sensor 120 can control the controlvalve 230 and the display device 240 by the wires W2 or the wirelesstechnique.

Expect for the water tap 200, the water supply 100 can be the toilet. Inother words, the gesture sensor 120 can be applied to the toilet. FIG.4A to 4C and FIGS. 5A and 5B are taken as the example to detailillustrate the embodiment of taking the toilet as the water supply 100.In addition, the toilet shown in FIG. 4A to 4C and FIGS. 5A and 5B aresimilar to the water supply 100. The similar technique features of boththe toilet and the water supply 100, such as the method that the gesturesensor recognize the gesture is omitted thereof.

FIG. 4A is a perspective view of the toilet in accordance with oneembodiment of the instant disclosure. FIG. 4B is a cross-section view ofthe toilet taken along the line I-I shown in FIG. 4A. Referring to FIGS.4A and 4B, the toilet 400 includes the toilet tank 410, the gesturesensor 120, the control valve 430 and the toilet bowl 450. The toilettank 410 provides the water to wash out the excrement and includes thewater outlet 412. The toilet bowl 450 connects to the toilet tank 410and has the water inlet 452 and the opening 454. The water inlet 452connects to the water outlet 412. The water outlet 412 can release theflow (not shown in FIGS. 4A and 4B) to the water inlet 452. The waterinside the toilet tank 410 can flow into the opening 454 through thewater outlet 412 and the water inlet 452.

The toilet tank 410 includes the front side 414 a and the back side 414b. The front side 414 a is sited between the opening 454 and the backside 414 b. The gesture sensor 120 is configured on the top of the frontside 414 a. Thus, while the user utilizes the toilet 400 to urinate, theuser can perform the control gesture in front of the gesture sensor 120to make the gesture sensor 120 sensing the control gesture. The controlvalve 430 is configured on the toilet tank 410 to control the flow.

The gesture sensor 120 can electrically connected to the control valve430 by the wire, or built up a signal link with the control valve 430 bythe wireless technique, such as Bluetooth. Thus, the gesture sensor 120can send the command to the control valve 430 to control the controlvalve 430 to release or stop the flow. Moreover, in the presentembodiment, the toilet tank 410 can be the water-storage tank. However,in other embodiment, the toilet 400 can be the toilet without thewater-storage tank. The toilet tank 410 can thus be the water pipe. Thetoilet tank 410 is not limited to the water-storage tank.

The gesture sensor 120 includes the light source 121, the image sensingunit 122 and the processing unit 123. While the light source 121 emitsthe light E1 to the hand H1, the image sensing unit 122 can capturevarious gesture images from various kinds of control gestures performedby the hand H1. The gesture images are formed by the light R1 (thereflection light of the light E1). The processing unit 123 can send thecontrol command to the control valve 430 according to the gestureimages. The control commands include the first flush command or thesecond flush command. In addition, the gesture sensor 120 can be withoutthe light source 121. The above mentioned gesture images can form by theexternal light reflected by the hand H1.

The control valve 430 can control the output amount of the flow as thefirst output amount according to the first flush command, and controlthe output amount of the flow as the second output amount according tothe second flush command. The first output amount is larger than thesecond output amount. The control valve 430 can control the outputamount of the flow by the duration of opening the flow.

Since the gesture sensor 120 is configured on the front side 414 a, thehand H1 can perform the control gesture of the second flush command infront of the gesture sensor 120 while the user utilizes the toilet 400to urinate. Therefore, the toilet 400 can release the flow with lowoutput amount to save water. On the other hand, the hand H1 can performthe control gesture of the first flush command in front of the gesturesensor 120 while the user utilizes the toilet 400 to empty the bowel,the hand H1 can perform the control gesture according to the first flushcommand in front of the gesture sensor 120. Thus, the toilet 400 canrelease the flow with high output amount to make sure that the excrementis wash out. In addition, the movement of the control gestures can bemaking the fist, opening the palm, waving the hand, turning the palm inthe clockwise direction, turning the palm in the counterclockwisedirection, or other gestures.

The toilet 400 can further includes the display device 440. The displaydevice 440 can indicate that the toilet 400 is in the open up conditionor in the shutdown condition. The display device 440 can electricallyconnect to the processing unit 123, or built up a signal link with theprocessing unit 123 by the wireless technique, such as Bluetooth. Thus,the processing unit 123 can send the command to the display device 440to control the display device 440. In addition, the processing unit 123in the present embodiment can send the open up command or the shutdowncommand. The method to generate the open up command and the shutdowncommand is similar to the previous embodiment, and the description ofthe same is omitted thereto.

FIG. 4C is a cross-section view of the display device taken along theline II-II shown in FIG. 4B. Referring to FIGS. 4B and 4C, the displaydevice 440 includes the light-emitting components 442 and the indicatortranslucent panel 444. The light-emitting components 442 can be thelight emitting diode or the cold cathode fluorescent lamp. The indicatortranslucent panel 444 can be the light transmissivepolymethylmethacrylate substrate or the glass substrate with theoperation screen. The operation screen can display the gestures andfunctions correspond to various commands (such as the first flushcommand and the second flush command), and can show by the letters orthe patterns. While the display device 440 show the operation screen,the light-emitting components 442 can emit the light toward theindicator translucent panel 444, so as to light up the indicatortranslucent panel 444.

FIG. 5A is a cross-section view of the toilet in accordance with theother embodiment of the instant disclosure. FIG. 5B is a circuit blockdiagram of the toilet shown in FIG. 5A. Referring to FIGS. 5A and 5B,the toilet 500 in the present embodiment is similar to the toilet 400,the similar technique features of both the toilet 400 and 500 is omittedtherefore. However, there exist the different between the toilet 400 and500. The toilet 500 further includes the control unit 542.

Specifically, the control unit 542 can be the processor and beelectrically connected to the gesture sensor 120. The control unit 542,the display device 541 and the gesture sensor 120 can be integrated intothe control panel 54 as shown in FIG. 5A. Thus, the user can manipulatethe control panel 54 by utilizing the gesture and control the controlvalve 430 to supply the flow with different output amounts.

In addition, the toilet 500 can include the heated seat 560. The heatseat 560 is configured on the toilet bowl 450 and electrically connectedto the control unit 542. The image sensing unit 122 can capturetemperature control gesture image from the temperature control gestureformed by the user. The processing unit 123 can send the command to thecontrol unit 542 according to the temperature control gesture, so as tocommand the control unit 542 to control the temperature of the heatedseat 560 according to the temperature control gesture image. The abovementioned temperature control gestures can be making the fist, openingthe palm, waving the hand, turning the palm in the clockwise direction,turning the palm in the counterclockwise direction, and the combinationof other gestures at random.

It's worth noting that, in other embodiment, the toilet 500 can furtherincludes another gesture sensor 120, the number of gesture sensor 120included in the toilet 500 can be at least two. The extra gesture sensor120 can be configured in the front side 414 a of toilet tank 410(referring to FIG. 4B). The seat cover of the toilet 500, such as theheated seat 560, can further configure the switch button (not shown infigure).

While the user utilizes the toilet 500 to urinate, the seat cover can beraised to trigger the switch button. Meanwhile, the switch button canswitch on the gesture sensor 120 position on the toilet tank 410 andcommand the gesture sensor 120 of the control panel 54 to shut off or bein the idle condition. Thus, the user can perform the control gesture tothe gesture sensor 120 in the front side correspond to the second flushcommand, so as to save the flush volume of the toilet 500.

While the user utilizes the toilet 500 to empty the bowl, the seat covercan be putted on the toilet bowl 450 to trigger the switch button.Meanwhile, the switch button can start up the gesture sensor 120 of thecontrol panel 54 and make the gesture sensor 120 of the toilet tank 410to shut off or be in the idle condition. The user sitting on andutilizing the toilet 500 can perform the control gesture to the controlpanel 54 corresponding to the first flush command, so as to supply theflow with high output amount. Thus, the excrement can be flush out forsure. In addition, the gesture sensor 120 in FIG. 5A can be configuredin the front side 414 a of the toilet tank 410 (Referring to FIG. 4B).The toilet 400 and 500 shown in FIG. 4A to 4C, FIGS. 5A and 5B are onlythe example and not limited to the present invention.

FIG. 6A is a schematic diagram of a display apparatus in accordance withone embodiment of the instant disclosure. Please refer to FIG. 6A. Thedisplay apparatus 600 may be controlled without touching a switch or aremote control. That is, even if the user does not touch the switch orthe remote control, the user still can control the display apparatus600. The display apparatus 600 may be used in the environment such as inkitchen, bathroom or hospital where it is not suitable or convenient forthe user to control the display apparatus 600 by touching the switch orthe remote control. For example, the display apparatus 600 may be abathroom television, a kitchen television or a medical displayapparatus.

The bathroom television is set in the bathroom and capable of operatingin humid environment such as in bathroom. Compared to generaltelevision, the bathroom television has better waterproof and wetfastness properties. In one embodiment, the kitchen television for usein kitchen is capable of operating in higher temperature and high oilsmoke environment. In addition, the medical display apparatus may beimplemented in a treatment instrument or in a medical examinationinstrument for display information. For example, the medical displayapparatus may be implemented in an endoscopy, a magnetic resonanceimaging (MRI) instrument, a computed tomography (CT) or a helicaltomotherapy treatment instrument for display.

In one embodiment, the bathroom television is taken as an example. Inthe kitchen, the user may be dealing with or cooking food ingredients sothat the user inconveniently holds the remote control or touches theswitch to control the kitchen television by hands stained with oil,water or food indigents (such as flour or raw meat). The displayapparatus 600 in accordance with one embodiment of the instantdisclosure may be controlled by the user without using any remotecontrol or touching the switch.

FIG. 6B is a circuit block diagram of the display apparatus shown inFIG. 6A. Please refer to FIG. 6A and FIG. 6B. The display apparatus 600includes a display unit 610 and a gesture sensor 120. The display unit610 may receive channel signals and show corresponding images. Thedisplay unit 610 may be a television such as a liquid crystaltelevision, a plasma television, an organic light emitting television orcathode ray tube television (CRT TV). In addition, the aforementionedchannel signals include audio signals and video signals.

The gesture sensor 120 may control the display unit 610. By using thegesture sensor 120, the user can control the television, i.e., thedisplay unit 610 without touching the television. Specifically, thedisplay unit 610 may include a controller 620 and a display device 640electrically connected thereto. The controller 620 may include amotherboard and electronic components disposed thereon. The displaydevice 640 having a pixel array can show image. The display device 640for example is a liquid crystal module (LCM), an organic light emittingdiode panel or a plasma display panel.

A signal link is established between the gesture sensor 120 and thedisplay unit 610. For example, the processing unit 123 of the gesturesensor 120 may be electrically connected to the controller 620 of thedisplay unit 610 through wires or a printed circuit board.Alternatively, both of the processing unit 123 and the controller 620have a wireless receiving/transmitting module, and the communicationbetween the processing unit 123 and the controller 620 can beestablished through their wireless receiving/transmitting modules. Thewireless receiving/transmitting module may be for example an infraredsignal receiving/transmitting module or a Bluetoothreceiving/transmitting module.

Accordingly, the gesture sensor 120 is capable of detecting the variousgestures performed by the user's hand H1 and transmits the correspondingcontrol commands to the controller 620 according to the gestures. Thus,the controller 620 can control the display device 640 according to thecontrol commands. The methods performed by the gesture sensor 120 toreorganize the gestures are described comprehensively in theabovementioned embodiments and omitted herein.

While a control gesture such as fist, palm, hand wave, or palm motionalong the counterclockwise direction C1 or the clockwise direction C2 isperformed by the user with the hand H1, the hand H1 can reflect thelight E1 to be the light R1. The image sensing unit 122 can receive thelight R1 and capture the image from the light R1. As such, the imagesensing unit 122 can capture gesture images from the various controlgestures performed by the user with the hand H1. The gesture images areformed due to the reflection of the light E1, i.e., the light R1.

It's worth noting that in the present embodiment, the gesture sensor 120includes the light source 121 to emit the light E1. However, in otherembodiment, it is not necessary for the gesture sensor 120 to includethe light source 121, and the image of the hand H1 can be captured bythe image sensing unit 122 directly. Specifically, the hand H1 canreflect the external light, which, for example, comes from the indoorlight or the outdoor sunlight. The image sensing unit 122 can capturethe image from the external light reflected by the hand H1. Similarly,the image sensing unit 122 can also capture various gesture images fromthe control gestures performed by the user with the hand H1. Therefore,the above mentioned gesture image is not limited to be formed by thereflection of the light E1 (which is light R1). The above mentionedgesture image can also be formed by the external light source.

The processing unit 123 may send a gesture control signal includingdifferent commands. In one embodiment, the gesture control signal mayinclude a turn-on command and a turn-off command which are respectivelycorresponding to different gesture images. The controller 620 decides toswitch the display device 640 on according to the turn-on command, andto switch the display device 640 off according to the turn-off command.Specifically, the controller 620 has a switching module (not shown inFIG. 6B), and the controller 620 controls whether the power is suppliedto the display device 640 through the switching module.

When the display unit 610 is in switch-off state (e.g. the displayapparatus 600 may be supplied with power of an external power source,but the display device 640 may be not supplied with power), the user canperform a control gesture which is corresponding to the turn-on commandahead of the gesture sensor 120. The image sensing unit 122 can capturethe control gesture image, and transmit the control gesture image to theprocessing unit 123. The processing unit 123 can transmit the turn-oncommand to the controller 620 according to the control gesture image sothat the display device 640 can be supplied with power and be switchedon.

When the display unit 610 is in switch-on state (e.g. the displayapparatus 600 is displaying image), the user can perform the controlgesture corresponding to the turn-off command with hand H1. Meanwhile,the processing unit 123 sends a turn-off command to the controller 620according to the control gesture image captured by the image sensingunit 122 to turn off the display unit 610.

In another embodiment, the gesture control signal sent by the processingunit 123 may include a channel switching command. The controller 620 canswitch the channel received by the display unit 610 according to thechannel switching command. The channel switching command is for examplea channel scan up command, a channel scan down command or a channelselection command. These channel switching commands are respectivelycorresponding to different control gestures. For example, the hand H1gesture of the open palm facing to the image sensing unit 122 and movingup is corresponding to the channel scan up command, and the hand H1gestures of the open palm facing to the image sensing unit 122 andmoving down is corresponding to the channel scan down command. If theuser performs a finger gesture which indicates a set of numbers, thefinger gesture is corresponding to the channel selection command and theset of numbers is corresponding to the channel number.

Namely, the controller 620 can scan the channel received by the displayunit 610 up in sequence according to the channel scan up command, andscan the channel down in sequence according to the channel scan downcommand. Specifically, the controller 620 includes a receiving module(not shown in FIG. 6B). When the user performs the gesture correspondingto the channel switching command, the processing unit 123 transmits thechannel switching command to the controller 620 so as to control thereceiving module to switch current channel to other channel.

In another embodiment, the gesture control signal may include a volumecommand. The processing unit 123 transmits the volume command to thecontroller 620 so as to adjust the value of the volume displayed by thedisplay unit 610. The volume command is for example an increasing volumecommand or a decreasing volume command, which are respectivelycorresponding to different control gestures. For instance, the hand H1gesture of palm rotating in clockwise direction is corresponding to theincreasing volume command, whereas the hand H1 gesture of open palmrotating in counterclockwise direction is corresponding to thedecreasing volume command. The processing unit 123 recognizes the user'sgesture motion and controls the controller 620 to execute thecorresponding volume commands displayed by the display unit 610.Specifically, the display unit 610 includes a speaker 630 which iselectrically connected to the controller 620. When the controller 620receives the volume command from the processing unit 123, the controller620 is capable of adjusting the volume through controlling the speaker630.

In the abovementioned embodiment, a link between the processing unit 123and the controller 620 is always maintained. However, in anotherembodiment, the link between the processing unit 123 and the controller620 is terminated until a startup gesture is captured by the imagesensing unit 122. When a termination gesture is captured by the imagesensing unit 122, the link between the processing unit 123 and thecontroller 620 would be interrupted.

That is to say, before the signal link between the processing unit 123and controller 620 is established, the display apparatus 600 would notwork even if the user performs the control gestures in front of thedisplay apparatus 600. However, the general methods, such as touchingthe display apparatus 600 or using the remote control, still can beperformed by the user to operate the display apparatus 600.Specifically, while the user wants to perform the operation of thedisplay apparatus 600, the user firstly has to perform the startupgesture. The image sensing unit 122 captures a startup gesture image,and the processing unit 123 transmits a startup command to thecontroller 620 according to the startup gesture image. As such, the linkbetween the processing unit 123 and the controller 620 can beestablished. In addition, in one embodiment, the user can performs thetermination gesture when the user wants to perform the operation of thedisplay apparatus 600 by the general methods. The image sensing unit 122captures a termination gesture image, and the processing unit 123receives the termination gesture image and then, terminates the linkbetween the processing unit 123 and the controller 620.

The display apparatus 600 may further includes an indicating element650. The signal link between the indicating element 650 and theprocessing unit 123 is established through a wire or wirelesscommunication network, such as through Bluetooth communication. Theindicating element 650 may indicate the link state between thecontroller 620 and the processing unit 123. That is, when the imagesensing unit 122 captures the startup gesture image performed by theuser, the processing unit 123 connects with the controller 620 accordingto the startup gesture image and controls the indicating element 650 toindicate the startup state. When the image sensing unit 122 captures thetermination gesture image performed by the user, the processing unit 123disconnects with the controller 620 and controls the indicating element650 to indicate the disconnected state.

In the embodiment shown in FIG. 6, the indicating element 650 mayinclude an indicating light, such as a light-emitting diode (LED) or acold cathode fluorescent lamp (CCFL). For instance, when the linkbetween the processing unit 123 and the controller 620 is established,the indicating light is turned on to indicate the startup state. Whenthe link between the processing unit 123 and the controller 620 isterminated, the indicating light is turned off to indicate thedisconnected state.

FIG. 7A is a schematic diagram of a satellite navigation apparatus inaccordance with one embodiment of the instant disclosure. FIG. 7B is acircuit block diagram of the satellite navigation apparatus shown inFIG. 7A. In the instant embodiment, the satellite navigation apparatus700 includes a display device 710, a controller 720 and a gesture sensor120.

The display device 710 has a pixel structure including a plurality ofpixels for displaying images. The display device 710 is for example aliquid crystal module (LCM), an OLED display panel or a plasma displaypanel.

The controller 720 may be configured in the inside or outside of thedisplay device 710, and a signal link between the controller 720 and thedisplay device 710 is established so that map information and coordinateinformation can be transmitted to and displayed on the display device710. Please refer to FIG. 7B, the controller 720 includes a positionreceiving module 721, a database 722 and a signal processing unit 723.The database 722 is used to store at least one map information, and theposition receiving module 721 may be a global positioning system (GPS)receiver for receiving at least one satellite signal.

The signal processing unit 723 electrically connects with the positionreceiving module 721, the database 722 and the display device 710.Furthermore, the signal processing unit 723 is used to receive andprocess the satellite signal transmitted by the position receivingmodule 721. The satellite signal is converted to coordinate information,which usually indicates the position where the satellite navigationapparatus 700 is located. As the satellite navigation apparatus 700 isbeing moved with a car driven by the user, the satellite signal iscontinuously received by the position receiving module 721 andtransmitted to the signal processing unit 723 to renew the coordinateinformation. In addition, the signal processing unit 723 retrieves themap information and transmits the map information to the display device710 in conjunction with the coordinate information for displaying.

After the user input a target address, the signal processing unit 723receives an input data and calculates target coordinate informationassociated with the target address. Furthermore, the signal processingunit 723 is capable of calculating at least one path informationaccording the target coordinate information, the coordinate informationand the map information. The path information includes a plurality ofthe coordinate points, the connecting line of which is a path extendingform the user's position to the target address.

The signal processing unit 723 is capable of controlling the displaydevice 710 to display the map information, the coordinate informationand path information. In one embodiment, the display device 710 may becontrolled by the signal processing unit 723 to display the mapinformation, the coordinate information and path information indifferent modes for example 2D, 3D or mixed display mode. The switchingbetween different modes (2D, 3D or mixed display mode) can be performedaccording to the user's instruction.

That is to say, the map information, the coordinate information and thepath information can be displayed in different modes on the displaydevice 710. In the embodiment of the instant disclosure, the gesturesensor 120 controls the controller 720 according to the user's handgesture so that the display device 710 can control the display mode ofthe map information, the coordinate information and the path informationaccording to the gesture performed by the user's hand H1. The detaildescriptions are explained as below.

Please refer to FIG. 7A and FIG. 7B. In the instant embodiment, thegesture sensor 120 includes a light source 121, an image sensing unit122 and a processing unit 123. The processing unit 123 can beelectrically connected to the signal processing unit 723 of thecontroller 720 through wire communication technique. In anotherembodiment, the processing unit 123 may establish a signal link with thecontroller 720 through wireless communication technique, such asBluetooth. By using wire or wireless communication technique, thegesture sensor 120 is capable of sending the gesture control signal tocommand the controller 720.

The light source 121 can emit the light E1 to the hand H1 of the user.The hand H1 can reflect the light E1 to be the light R1. By utilizingthe light E1, the image sensing unit 122 can capture various gestureimages from the various control gestures performed by the hand H1. Thecontrol gestures includes making a fist, opening the palm, waving thehand, rotating the palm in clockwise direction, rotating the palm in thecounterclockwise direction, or other kinds of gestures. The gestureimage is formed due to the reflection of the light E1, i.e., the lightR1.

The processing unit 123 can send several gesture control signals to thesignal processing unit 723 of the controller 720 according to thegesture images. The signal processing unit 723 of the controller 720 mayswitch the display mode of the map information and coordinateinformation on the display device 710 according to the gesture controlsignal.

Specifically, the gesture control signal may include a first switchingcommand for switching the 2D display mode to 3D display mode and asecond switching command for switching a stereoscopic map (the 3Ddisplay mode) to a planimetric map (the 2D display mode). The firstswitching command and the second switching command are respectivelycorresponding to different gestures. For example, the first switchingcommand is corresponding to a two-fingered gesture, and the secondswitching command is corresponding to a three-fingered gesture. When theprocessing unit 123 recognizes the gesture corresponding to the firstswitching command, the processing unit 123 transmits the first switchingcommand to the controller 720 so as to switch the display mode to 2Ddisplay mode for displaying the planimetric map. When the processingunit 123 recognizes the gestures corresponding to the second switchingcommand, the processing unit 123 transmits the second switching commandto the controller 720 so as to switch the display mode to 3D displaymode for display the stereoscopic map.

In addition, the gesture control signal may include a zoom-in command, azoom-out command, a panning command and a scrolling command, which arerespectively corresponding to different control gestures. For example,the zoom-in command is corresponding to the gesture of moving the fingeraway from the thumb, and the zoom-out command is corresponding to thegesture of moving the finger toward the thumb. The image sensing unit122 captures the gesture image of the user, and the processing unit 123transmits the gesture control signal to the controller 720 so as tocontrol the scale of map information displayed on the display device 710to be enlarged or diminished.

Furthermore, the user may control the satellite navigation apparatus 700to be switched on or off through the gestures. Specifically, the usercan perform a switch-on gesture and a switch-off gesture so as tocontrol the satellite navigation apparatus 700. The switch-on gesture isfor example opening and closing palm repeated three times and maintainedin open-palm state at the last time for three seconds. The switch-offgesture is for example closing and opening palm repeated three times andmaintained in closed first state for three seconds. When the imagesensing unit 122 captures the switch-on gesture, the processing unit 123sends a switch-on command to the controller 720 so that the controller720 control the display device 710 to be turned on according to theswitch-on command. When the image sensing unit 122 captures theswitch-off gesture, the processing unit 123 sends a switch-off commandto the controller 720 so that the controller 720 control the displaydevice 710 to be turned off according to the switch-off command.

The satellite navigation apparatus 700 of the instant embodiment mayinclude a microphone 701 electrically connected to the controller 720.When the microphone 701 is turned on, the user can input the targetaddress through the microphone 701. The controller 720 receives the datainputted by the user and calculates target coordinate informationassociated with the target address. In the instant embodiment of thepresent disclosure, the user can perform a gesture to turn on themicrophone 701 so that the target address can be inputted by the user'voice.

Specifically, the image sensing unit 122 captures the control gestureimage, and the processing unit 123 transmits a voice input command or anend command to the controller 720. That is to say, the gesture controlsignal sent out from the processing unit 123 may include the voice inputcommand or the end command. In the instant embodiment, the voice inputcommand and end command are respectively corresponding to differentcontrol gestures. When the controller 720 receives the voice inputcommand transmitted by the processing unit 123, the controller 720controls the microphone 701 to be turned on for receiving the user'svoice message according to the voice input command. When the controller720 receives the end command transmitted by the processing unit 123, thecontroller 720 controls the microphone 701 to be turned off according tothe end command. It is worth nothing that, in the instant embodiment,the user inputs the target address through the microphone 701, whichdoes not intend to limit the instant disclosure, and the other means forinputting the target address can be taken by the user, such as through atouch panel.

In another embodiment, the satellite navigation apparatus 700 mayinclude a speaker 702 for playing sound. The speaker 702 is electricallyconnected to the controller 720. In addition, the speaker 702 and themicrophone 701 may be two independent devices or be incorporated intoone voice receiving/playing module. In the instant embodiment, the usercan controls the execution or termination of the voice guiding functionby performing the gestures.

Specifically, when the image sensing unit 122 captures a voice guideexecuting gesture performed by the user, the processing unit 123transmits a voice guide executing command to the controller 720. Thecontroller 720 converts the path information into sound signal, andcontrols the speaker 720 to play the voice according to the soundsignal. As such, the user can be guided by the voice and drive accordingto the path information. When the image sensing unit 122 captures avoice guide terminating gesture performed by the user, the processingunit 123 transmits a voice guide terminating command to the controller720. The controller 720 terminates the transmission of the sound signaland the speaker 702 stop to play. That is to say, the gesture controlsignal transmitted by the processing unit 123 may include the voiceguide executing and terminating commands, which are respectivelycorresponding to different gestures.

The satellite navigation apparatus 700 of the instant embodiment alsoincludes an indicating element 740. The indicating element 740 may be anindicating light electrically connected to the processing unit 123 orestablished a signal link with the processing unit 123 by the wirelesstechnique, such as Bluetooth.

That is, when the image sensing unit 122 captures the startupgesture performed by the user, the processing unit 123 establishes asignal link with the controller 720 according to the startup gestureimage, and controls the indicating element 720 to indicate the startupstate.

In one embodiment, when the image sensing unit 122 captures a startupgesture image performed by the user, the processing unit 123 establishesthe signal link with the controller 720. That is, before the signal linkbetween the processing unit 123 and the controller 720 is established,the satellite navigation apparatus 700 does not work even if the userperforms the control gestures in front of the display apparatus 600.However, the user can operate the satellite navigation apparatus throughthe other means.

When the user wants to terminate the gesture operation of the satellitenavigation apparatus 700, the user can performs a termination gesture.When the image sensing unit 122 captures a termination gesture image,the processing unit 123 terminates the signal link between theprocessing unit 123 and the controller 720, and controls the indicatingmember 740 to be turned off.

In the instant embodiment, the aforementioned commands, such as thestartup command, the zoom-in command, the zoom-out command, the voiceinput command, the link termination command and so on, and the gesturesrespectively corresponding thereto can be displayed on the displaydevice 710 through the on-screen display techniques so as to instructthe user to operate the satellite navigation apparatus 700 by performingthe gesture. Accordingly, while the user is driving the car, the usercan control some operations of the satellite navigation apparatus, suchas inputting address, enlarging or reducing the map, executing the voiceguide and so on.

The apparatus having gesture sensor in one embodiment of the instantdisclosure may be a golf training apparatus. In the instant embodiment,the golf training apparatus would be described in connection with FIG.8A, FIG. 8B and FIG. 8C in detail below. FIG. 8A is a schematic diagramof a golf training apparatus in accordance with one embodiment of theinstant disclosure. FIG. 8B shows a user's image captured by an imagecapturing unit shown in FIG. 8A, and FIG. 8C is a circuit block diagramof the satellite navigation apparatus shown in FIG. 8A. The golftraining apparatus may be used to detect the user's pose through thegesture sensor so that the user's pose can be corrected.

The golf training apparatus 800 includes a practice device 810, thegesture sensor 820 and the instructing device 830. The gesture sensor820 establishes a signal link with the instructing device 830.

The practice device 810 may include a fairway 811 and a ball 812. Thefairway 811 is designed according to the simulation of the golf course.The user can practice swing or putting to hit the ball 812 placed on thefairway 811. The fairway 811 may be a swing practice mat or a puttingpractice mat. FIG. 8A shows the user standing on the fairway 811 holdsthe golf club with a hand H2 and aims the ball 812 to make a swingpractice. During swing, the hand H2 may move along a trace T. As theball 812 is impacted by the golf club, the user's hand H2 is locatedjust at the lowest position of the trace T. For the user who ispracticing swing or putting, whether the posture of the user at momentof impact is correct would significantly affect the result of theimpact.

Please refer to FIG. 8B, the gesture sensor 820 includes an imagesensing unit 821 and a processing unit 823. Both of the processing unit823 and the processing unit 823 establish a signal link with theinstructing device 830. As the user starts to practice, the imagesensing unit 821 captures at least one user's image. The user's imagecaptured when the user's hand is located at the lowest position of thetrace T. The user's image may show the side view of the user whichincludes at least one hand image and at least one leg image. The handimage may include a first image and an arm image, and the leg image mayinclude a thigh image and a calf image.

The gesture sensor 820 may further include a light source 825 which isutilized to emit a light toward the user and electrically connected tothe processing unit 823. The image sensing unit 821 is located adjacentto the light source 825, and the user's image is formed due to thereflection of the light. In one embodiment, the light is invisiblelight, however, in another embodiment, the light may be sunlight oremitted from an indoor lamp.

The processing unit 823 receives the user's image and recognizes thehand image and leg image to proceed with the analysis. Specifically, theprocessing unit 823 defines a first axial line L1 form the hand image,and defines a second axial line L2 form the leg image. The first axialline L1 and the second axial line L2 form an angle θ. The angle θ iscorresponding to the angle formed by user's arm and user's leg as theball 812 is impacted.

The processing unit 823 may store at least one reference angle which isassociated with a correct swing posture, and the reference angle has apredetermined range. In another embodiment, the processing unit 823 maystore many different reference angles which have different ranges andrespectively corresponding to different conditions. For example, thereference angle has the predetermined range from 10 to 170 degreecorresponding to the swing practice, and another reference angle hasanother predetermined range from 2 to 85 degree corresponding to theputting practice. In addition, the predetermined range may be setaccording to the user's height or the types of the golf club used by theuser during practice.

In one embodiment, the gesture sensor 820 may further include a displaymodule 824, which may be a liquid crystal display module or a touchpanel display module. The processing unit 823 may control the displaymodule 824 to show the conditions, such as height, the type of the golfclub, the type of practice and so on, so that the user can select theappropriate conditions. In one embodiment, before the user starts topractice, the user can perform the gesture to select the conditions. Forexample, the display module 824 shows two practice options, such asswing practice and putting practice, which are respectivelycorresponding to different gestures. For instance, selecting the swingpractice is corresponding to a one-figure gesture, and selecting theputting practice is corresponding to a two-finger gesture. The imagesensing unit 821 captures the gesture performed by the user, andtransmits to the processing unit 823. The processing unit 823 recognizesthe gesture image to determine the conditions selected by the user, andcalculates the predetermined range of the reference angle whichsatisfies the requirements of the conditions. After the predeterminedrange of the reference angle is calculated, the processing unit 823determines whether the measured angle θ falls within the predeterminedrange. When the measured angle θ falls out of the predetermined range,the processing unit 823 sends an instructing signal to the instructingdevice 830 to remind the user to correct his posture.

The instructing device 830 may be one or more indicating lamps and/or aspeaker. The indicating lamps may be LED lamps having one or moredifferent colors to indicate the measured results. In another example,the indicating lamps are used to display the reminding message with theinstruction for correcting the user's posture. Specifically, if themeasured angle θ falls within the predetermined range, which representsthe user's posture is correct during impacting the ball 812, theindicating lamps would emit green light. If the measured angle θ fallsout of the predetermined range, which indicates the user's posture iswrong during impacting ball 812, the indicating lamps would emit redlight. In addition, the speaker may play many kinds of indicating soundsassociated with the measured results. For example, the indicating soundsmay be vocal sounds so as to instruct the user on how to adjust theposture by vocal, or may be a part of music for reminding the user.

In another embodiment, the golf training apparatus 800 may be used tomeasure the swing velocity as the golf club impacts the ball 812.Specifically, the image sensing unit 821 may capture a plurality of thesequential user's images at different times and transmit to theprocessing unit 823. Each of the sequential user's images may shows theside view of the user and include at least one hand image. At least oneof the sequential user's images is captured when the user's hand H2 islocated at the lowest position of the trace T.

The processing unit 823 receives the sequential user's images andrecognizes the hand image. The processing unit 823 is capable ofcalculating the relative distance between the user's hand H2 and thegesture sensor 820 according to an occupied area of the hand image inthe user's image. Specifically, the processing unit 823 may furtherinclude a database for storing a reference table. The relationshipbetween the occupied area of the hand image and the relative distancewould be listed in the reference table. Accordingly, after theprocessing unit 823 recognizes the hand image and calculates theoccupied area of the hand image in the user's image, the relativedistances between the user's hand H2 and the gesture sensor 820 atdifferent times can be acquired according to the reference table. Theprocessing unit 823 is capable of calculating the swing velocity of theuser according to the variation of the occupied area of the hand imagewith the time change. Especially when the user's hand H2 moves along thetrace T to the lowest position of the trace, the instantaneous velocityof the user's hand H2 can be calculated.

The database of the processing unit 823 may store a velocity range. Theprocessing unit 823 analyzes the swing velocity according to thesequential user's image and determines whether the swing velocity fallswithin the velocity range. When the swing velocity falls out of thevelocity range, the processing unit 823 transmits the instructing signalto the instructing device 830 to inform the user.

In addition, because the swing velocity in swing practice is differentfrom that in putting practice, the database of the processing unit 823may store several sets of the velocity ranges which are respectivelycorresponding to different conditions. Before starting to the golfpractice, the user can set the types of practice, and the processingunit 823 would select the appropriate velocity range according to theuser's selection.
